BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of upper furnaces in which the front and back sides of a dough are arranged at regular intervals in the circumferential direction at the top and bottom while rotating a grill on which rice crackers are placed by a turntable. The present invention relates to a rice cracker for baking while simultaneously and alternately firing and cooling using the thermal power of a lower furnace.

[0002]

2. Description of the Related Art Conventionally, a rice cracker baking machine is configured such that the rice cracker dough is placed on a conveyor and rotated, and while the rice cracker dough is sequentially inverted by hand, the dough front and back are baked using the heat of a lower heat source. By inserting the two ends of the grid support shaft through the bearings fixed on the left and right sides of the top surface of the frame and parallel to the length direction, multiple grills can be extended in the length direction of the frame. At a fixed interval, it is rotatably supported in the same direction, and the grill is inverted from the horizontal position to the adjacent grill by the grill reversing mechanism, so that the rice crackers can be transferred onto the adjacent grill. Meanwhile, there is known one in which the front and back of the dough are configured to be baked using the thermal power of a lower heat source.
